Thanks for the update – I’ll look forward to more information.
As I said, there are different places to upload files, one of which might work for you:
1. The Media/Add New submenu “Upload New Media”, will add items to the Library independent of any post. Try this one to see if the Media Manager Modal Window is the only source of trouble.
2. The Edit Post/Add Media (Media Manager Modal Window), on the “Media Library” tab where the existing Media Library items are shown. You can drag & drop on top of the existing items. This is the route I tried with good results.
3. The Edit Post/Add Media (Media Manager Modal Window), on the “Upload Files” tab, where you can either drag & drop or click “select Files”. This also worked for me, but may give different results.
I need to know which of those three places is giving you trouble and if any of the three are working at all. You can also try two other experiments, which would be very helpful.
1. Go to the Settings/Media Library Assistant General tab, scroll down, uncheck the “Media Manager Checklist meta boxes” and “Media Manager Flat meta boxes” options, then scroll to the bottom of the page and click Save Changes. This will disable the new code in v1.80 that uses the ATTACHMENT DETAILS area. It is the most likely source of trouble.
2. Go to the Settings/Media Library Assistant General tab, scroll down, uncheck the “Enable Media Manager Enhancements” option, then scroll to the bottom of the page and click Save Changes. This will disable all of the MLA code; nothing will be downloaded to the Media Manager Modal Window. If this fixes the trouble you can use the other parts of MLA without disturbing your media uploading.
Anything more you can tell me will be useful. Thanks for your patience and all your help.
